Basic schemes of an electric equipment

The general information

Before to start diagnostics of refusal any of contours, check up a condition of safety locks protecting it and chain breakers (if the last are provided). Make sure of completeness of gymnastics of the battery and check up quality of contact connections of the wires connected to its polar plugs (Current leaving and service see the Head).

By search of refusal of a concrete contour first of all also check quality of contact connections of its electroconducting. At рассоединении electric sockets try to pull only for their cases, and at all for a plait of wires.
